2 Claims.

My invention relates to improvements in dice and the method of making the same. An object of my invention is to provide a simple and convenient device of the character specified; a further object of my invention is to provide a die formed of sheet material; a further object of my invention is to provide a die which may be constructed at small cost; a further object of my invention is to provide a novel means for marking indicia on the faces of dice; and a fur: ther object of my invention is to provide a new, useful and inexpensive means for making dice.

I accomplish these and other objects by my invention, a preferred embodiment of which is illustrated in the accompanying drawing, in which Figure 11s a plan view of the blank from which the die is formed,

Figure 2 is a view of the die. assembled, and

Figure 3 is a section of the same.

Similar characters of reference refer to similar parts throughout the several views.

My improved die is preferably formed by stamping out from a sheet of suitable material, such as sheet iron or the like, a cruciform blank 25 as illustrated in Figure 1 comprising six equal squares or spaces to form the six sides of the die, the dividing lines between the squares being shown in Figure 1, by dotted lines dividing the squares.

In these squares or spaces are punched holes 1 representing indicia of value.

The cutting of the blank and the punching of the holes may comprise a single operation.

Referring to the blank shown in Figure 1, it

comprises a central square or space 6, and three squares 2, 3 and 5, of equal area extending from three sides of the central square 6, and a long arm containing the squares I and 4 extending from the fourth side of the central square 6.

This blank, above described, is stamped or folded into the form of a cube by bending the squares 2, 3, 5 and 4 to positions at right angles to the plane of the square 6, and folding over the square I, to a plane parallel to the plane of the square 6, thus forming a cube.

The sheet metal of which the die is formed may be of any suitable gauge or material but I prefer to use a thin sheet iron whereby the die is light and strong. 7

The exposed edges may be slightly rounded as illustrated in Figure 3, or otherwise finished to remove sharp edges and the die may be plated or colored as desired.

Having thus described my invention, what I claim is: r

1. A sheet metal die comprising a central square section, four square sections integral with and bent up on each margin of the said central square section, and a square top section integral with one of the said last mentioned sections and bent over at right angles thereto forming the sixth side of the die, the said sides being self supporting.

2. A die formed by bending a cruciform blank of sheet metal to a hollow cubical form, the sides of which are self supporting with no attaching means between the free edges of the metal.
